• Kendrick Lamar had a show-stopping moment when he took the stage at last night's Grammy Awards, but Adele's performance didn't match the greatness of her past live efforts. Lamar started his performance Monday appearing beaten, in handcuffs, with chains around his hands and a bruise on his eyes. He went on to fuse rap, jazz, reggae and African sounds for a commanding performance as he rapped The Blacker the Berry and the Grammy-nominated Alright passionately.

• This morning, Russia rebuffed claims that its warplanes struck a hospital supported by Doctors Without Borders in northern Syria in yesterday's airstrikes that killed at least nine as Syrian government forces and a predominantly Kurdish coalition made gains against rivals in the country's north. In Moscow, President Vladimir Putin's spokesman Dmitry Peskov noted that Syria's ambassador to Russia said the hospital was destroyed by the Americans.
